PACIFIC MODEL 38

Manufactured for Pacific Radio Co. Ltd by Radio Corporation of New Zealand in 1937.

The Pacific model 38 used a spiral line of light to indicate the frequency. Only one cabinet design has been sighted, which is very conventional by the standards of their earlier Art Deco inspired cabinet designs

The spiral line of light is generated by two aluminium discs, one with a spiral-shaped slot cut in it and the other with a large opening with curved sides. They rotate independently of each other and in sync (but at different speeds) to the tuning gang in order to produce a line from the center out to a point that indicates the position of the tuning gang.

Valve Lineup: 6D6, 6A7, 6D6, 6B7, 42, 80 and 6E5 Magic Eye

I.F. Frequency: 456kc/s

Chassis Notes: 3-band chassis covering broadcast 550 - 1500kHz, Intermediate SW 2.1 - 6MHz and SW 6 - 18MHz. The chassis uses a unique spiral dial tuning system with an effective tuning distance of over 2 feet and fast / slow tuning to provide very good control of the frequency. The spiral tuning system is complex though, and unless its been restored it always seems to be broken on sets found today. The dial assembly consists of either a red-tinted spiral line of light or a red dot (depending on brand) that indicates the frequency on a novel trio of spirals for the three bands. The band selector slightly rotates the system so that the dot or the end of the line aligns with the correct band. Setting this up takes some patience and trial-error (There is some indication that there was to be a service bulletin from RCNZ for the dial assy, but it has never been sighted).

All documented models using the same chassis
